2 Claims. I(Cl. 119-7-25) The invention relates to an improvement vin poultry roosts tending to prevent diseases and to maintain the normal healthy condition of the fowl and embodies a preferred arrangement of parts later described which may be suspended from the roof of a chicken house, or otherwise' supported in a leveled position. The device includes pan means adapted to hold a suitable fluid l adapted'to give olf a gas which upon rising penetrates the feathers of the fowl and acts to destroy lice, mites and the like on the fowl.

In the drawing,y Fig. 1 represents a plan View of the chicken roost in accordance with our design with the left hand portion of the roost proper broken away to disclosev the supporting pan. Fig. 2 shows a side view of the composite device.

v Fig. 3 represents a sectional View as takenk along theline III-I II in Fig. 1 and looking in the direction of the arrows. Similar numerals of reference indicate corresponding parts throughout all the gures of the drawing.

Referring to the drawing; a unit pan structure includes a plurality of longitudinally extending channel-like sheet metal pan elements arranged in rows, spaced apart a proper distance; and a plurality of transverse channel-like pan elements integral with said first mentioned pan elements. l.The bottom of the unit structure lies in a common plane, the intent being that it shall be suspended or supported in a horizontal plane or so that` a desired disinfecting liquid may be poured into a longitudinal pan section through the inlet I2 and circulate freelyv through the transverse pan elements-|011 into the otherV longitudinal pans IIJ and to fill the unit structure to a desired depth as later explained. At I I is seen a drain plug, normally kept closed, except when it is desired to drain the unit pan structure. 1

We cover the entire pan structure IIl and Illy with the wooden roost frame I3 and |321, the upper section preferably overhanging and capping the top of the channels'lll as seen in Fig. 3 and with the lower portion` I3: closelyy filling the upper portion of the pan I0. The fluid I5 which is of a proper mixture of medicinal quality adapted to give off a gas is next admitted through the filler cap I2 leaving a space I4 between the liquid I5 and the bottom of the members |32: for

gas circulation. The suspension of the wooden roost `frame by the overhanging cap portions serves to establish a definite depth area available for the uid without the liquid touching the Wood elements; this is very desirable as the actual contact of the liquid with the wooden parts,

might by capillary action cause the liquid to contact the fowl and render eggs nonfertile. At spaced intervals vertical holes I6`are centrally f arranged in the members I3 and |311, Figs. 1 and 3, these-holes at the top are provided with ring like members I'I seated within the enlarged upper part I8 off the hole I6. Integral with the ring I'I isV a screen cap such as I9 which is soldered or otherwise affixed to the ring I'I in any well understood manner and the screens for strength and ease of cleaning form a curved cap as seen in Fig. 3. v

The spacing of these holes I6 and screens I9 is such that a fowl may seat over-the screen, and

'whereby the gaseous vapor arising from thepan v I3 will readily penetrate the feathers and attack and kill mites, lice and the like. When the liquid I5 becomes dirty or has lost its efciency, it

channel-like pan elements transversely con nected by a plurality of channel-like pan elements; a roost structure comprising longitudinal and transverse members capping and loosely depending within the several pan elements of the unit structure; and vertical passages arranged at spaced intervals inthe roost structure and a screen-like cap for each passage.

2. In roosts of the'class described; a unit panlike structure arranged in a common plane and comprising a plurality of longitudinallyextendingjchannel-like pan elements, closed at their ends, and transversely connected by a plurality of channel-like pan elements;` and awooden roost comprisingfa plurality of longitudinally extending members transversely connected by a plurality of transverse members; said roost ,members capping and loosely depending within the several pan elements of the unit pan structure and having vertical passages arranged at spaced intervals and covered by a screen-like cap; said unit pan structure being adapted to receive a fluid to a depth short of contact with the roost structure substantially as specified.
